Hi,

So i think i have passed the beginners level of c programming. My last program had a nice menu, you input sets of data through options, it read from text files, saved to textfiles, did calculations and displayed it, used arrays etc.

Now i want to try and learn some cooler stuff.

My last program saved its output data to a text file, so the user could then input it to excel, and draw graphs. Is there a way i can open excel (assuming the location of it on the users computer) and input the data to cells there???

Every time you closed my last program and re opened it, you had to reenter data, does anyone know a good way to have an "open recent" option?

If i have a load of sets of data - a 100 say, please can you point me in the direction of drawing a text graph of those data points, with | __ as the axis and . as a point on the graph?

Thanks guys
